Title

Fishing Line Breaking Point

Broad Question

Does 10lb. test break at 10lbs. of weight?

Specific Question

Do different brands of 10lb. test fishing line affect the weight it can withstand before breaking?

Hypothesis

It is hypothesized that the Spiderwire EZ Mono 10lb. test will exceed the manufactures weight limit. This is based on the motto of the product.

Variables

Independent Variable:

Brands of fishing line

Dependent Variable:

Breaking point weight

Variables That Need To Be Controlled:

10lb. test line, Same five gallon buckets, same length of different brands of line, Same type of sand to put in the bucket. Same knots used to tie line to bucket and hook, Same method of adding sand to bucket

Vocabulary List That Needs Explanation

Pound Test- amount of pressure that can be put on a line before it breaks
Force- strength or power exerted upon an object





General Plan


For the experiment take three different types of 10lb. test fishing line. One at a time take one brand of fishing line and tie it to the metal hook connected to the top of the garage. Then tie the other end of the fishing line to a five gallon bucket with lines on it that show where 5, 7.5, 10,12.5, and 15 pounds of sand are. Next slowly pour the sand into the bucket, until the fishing line breaks. This procedure will then be repeated using the two other brands of 10lb. test fishing line.

Potential Problems And Solutions

The bucket of sand could drop causing it the crack and spill, I would go and get another five gallon bucket down stairs and go get more sand at the Town Hall.

Safety Or Environmental Concerns

The fishing line could snap unexpectedly and fall on my foot.

Background Research


-Fishing line made from a single fiber of plastic is Monofilament-Most fishing lines are now monofilament because cheap to produce-Made by melting and mixing polymers and then pushing mixture through tiny holes-The extruding process controls the thickness and test strength-Weakened when exposed to sunlight and heat-Can absorb water -Check breaking strength by using a machine developed to measure line breakage-To test a line sample you must first wind one end around a small disc on the measuring end of the machine, and clip it in place-Then connect the other end of line in the same manner to a larger disc at the other end of the machine-When the test begins, the larger wheel rotates at a constant speed until the line snaps-The final poundage is displayed on the measuring device, each spool of line is supposed to be tested three times to get an average-Berkley Trilene is made out of nylon monofilament-Pound test is the amount of pressure that can be put on a line before it breaks. The larger the pound test, the stronger the line.- Nylon monofilament accounts for more than two-thirds of all fishing lines sold-”Monofilament” is a word that means a single strand of line- Scraping lines, all in a dry state, repeatedly over sandpaper, is how manufactures test abrasion-Stretching is a major issue when testing line because too much can make the line more vulnerable-The average percent of stretch in nylon monofilaments in a wet state is a range of 10 to 25 percent-Once you tie a knot in a fishing line, it becomes weaker-The same knots that are used for nylon monofilaments are not as good with braided lines and fused microfilaments

Detailed Procedure


1. Purchase three different brands of 10lb. test fishing line; Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex.2. Take a five gallon bucket and fill it with fifteen pounds of sand from the Town Hall.3. Screw the metal hook into the top of the garage, to tie one end of the fishing line to test the strength.4. Take another 5 gallon bucket and place it onto a scale, slowly pour in the sand and mark a line with sharpie at the 5, 7.5, 10, 12.5, and 15 pound marks.5. Using one brand of fishing line, cut a 6.5ft. piece of line.6. Tie one end to the metal hook and the other to the bucket handle. (Make sure to leave no more than a 6ft. span of line between the bucket and hook.7. Slowly start to pour sand into the 5 gallon bucket with a measuring cup, once you reach each marked point, stop and record your data.8. When the line snaps, put the bucket of sand onto the scale and record the final weight of the bucket.9. Repeat steps 5 through 7 for 10 trials for each brand of fishing line

Data Analysis


Conclusion


An experiment was conducted to see what brand of ten pound test fishing line had the highest breaking point. The independent variable was different brands of 10lb test fishing line, and the dependent variable was breaking point force. The experiment that was conducted used three brands of fishing line, Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex. Berkley Trilene held the most weight. The end result of the experiment was that Berkley trilene came in first with an average breaking point weight of 9.1 pounds. Spiderwire EZ Mono came in not that far behind with an average breaking point weight of 6.7. Just to reiterate, these brands of fishing line are 10 pound test, meaning that they should withstand a weight of 10 pounds of force. Zebco Omniflex came in with an average of 5.05 pounds.






Discussion


The experiment question was, do different brands of 10 pound test affect the weight it can withstand before breaking? The answer to this question is yes, the three different brands of 10 pound test fishing line all had different breaking points. The hypothesis that was made was not supported by the results. In the hypothesis, Spiderwire EZ Mono should have withstood the most force, but after conducting the experiment, Berkley Trilene can out on top with an average breaking point weight of 9.1 pounds, while Spiderwire EZ Mono only had an average breaking point of 6.7 pounds. In the experiment, there was a relationship between the brand of fishing line and the amount of force it can hold. The experiment showed that each brand had a pattern, in the sense that all of the breaking weights for that brand were very similar. There were only a few minor problems throughout the experiment, and were easily resolved. One of the main problems was that the fishing line would sometimes have a knot or tension, which would easily mess up my results. This problem was easily fixed by just getting another six and a half foot piece of line. Another problem that was faced while conducting the experiment, was when the sand would come out of the bucket to fast or in a big clump, making the bucket shake and move, and sometimes making the line break. This would then cause the trial to be redone.
If the experiment were to be run again, I would try to find a way to slowly and evenly distribute the sand around the inside of the bucket. I would also use non- rock sand, because the rocks would cause tension in the line when it would bounce around. The last thing that would have to be changed in the experiment, would be to tie different knots around the bucket handle and metal hook. This caused only one problem, that on the fifth trial using Spiderwire EZ Mono, the bucket fell off the line because of a poorly tied knot around the handle. The research that was found off the internet to find out what the different brands of fishing lines were made out of, and how each and every one of the companies test their lines. Someone in the future could look at the results and see how the experiment was conducted and what results were found. They could then take what they learned from the experiment and make a more efficient and/or easier way to test fishing line in the future. The results of the experiment can be of benefit to all avid sportsmen and fishermen alike. This information can be used to help avid fishermen maybe think twice before they use Zebco Omniflex or Spiderwire EZ Mono, and to inform them of the results and discoveries. It could also benefit the fishing line companies themselves, to show them how the experiment was ran and show them how their line did next to their other competitors.

Abstract


An experiment was conducted to see what brand of ten pound test fishing line had the highest breaking point. The independent variable was different brands of ten pound test fishing line, and the dependent variable was breaking point force. The experiment that was conducted used three brands of fishing line, Berkley Trilene, Spiderwire EZ Mono, and Zebco Omniflex. Berkley Trilene held the most weight. The hypothesis for this experiment was that the Spiderwire EZ Mono, would be the brand of fishing line that would hold the most force. The hypothesis that was predicted, didn’t match the result of the experiment. The end result of the experiment was that Berkley Trilene came in with an average breaking point weight of 9.1 pounds, the highest of the three brands. Spiderwire EZ Mono had a breaking point of 6.7 pounds, and Zebco Omniflex ha a breaking weight of 5.05 pounds. It was a surprise that Spiderwire EZ Mono did not hold the most force, because all of the research that was done said that Spiderwire is the highest quality line. Fishermen should now be using Berkley Trilene for fishing line because of the weight it held.
